What does it mean when it is used in plural form and meaning the heart as the seat of feelings ?Does it mean the heart of plural people ? Or, can it mean the heart of one person ?L&S gives no sample sentence for 2. and 3. with plural forms.

But pectus (1. chest / 2. heart as the seat of feelings) in plural form can mean the heart of one person.OLD explains so. (Mr. Adrianus told me so last time.)

Domum reditus sum et in OLD inquiro. De usu pluraliter pro numero singulari apud poetas, praeeuntia autem exempla ibi non inveni.I'm back home, looking in OLD, but can't see examples to illustrate what it says about the plural usage in a singular sense with poets.

OLD wrote:cor cordis, n...N.B.: the pl. is often used in a sg. sense by poets.

Thank you.Do you remember any article on such plural usage in Gildersleeve ? You don't have to look into it. I do it. Just tell me only when you remember something or have some advices on researching about this problem.

Is it odd to call you "Mr. Adrianus" ?You are much older than I, and I feel I have to show reverence in calling your name, but I don't know how to do so in English.

I would just call him adrianus as he calls you Junya with no added titles. This is not a class where some degree of formality and hierarchy is required.In addition, Age does not necessarily merit more respect or suggests being wiser than a youngerperson. This is not to imply that adrianus is not wise or worthy of respect (he's proven hisworth countless times on this forum) but your question implied anyone older should automatically be treated with the utmost respect and obedient deference.
